Straw Rice Husk Wood Chips Sawdust Pellets Automatic Production Line

A pelletizing system is a continuous processing system that physically compresses forest waste (such as sawdust, wood shavings, and branches) into pellet fuel. From raw material pretreatment to finished product packaging, the entire line typically follows a six-step process: crushing - drying - pelletizing - cooling - screening - packaging, achieving efficient raw material conversion and commercial output.

Detailed Explanation of the Complete Line Equipment Components and Functions
1. Raw Material Crushing System (Crusher)
Function: Crushes coarse materials such as raw wood, branches, and scraps into 3-5mm pellets, providing a suitable particle size for subsequent pelletizing.
Recommended Configuration:
Small Line: Hammer Mill
Medium-to-Large Line: Drum Chipper and Crusher

2. Raw Material Drying System (Dryer)
Function: Drys sawdust with a moisture content exceeding 18% to 12-15%, ensuring a high yield and pellet quality.
Recommended Equipment:
Airflow Dryer (Suitable for Small Production Lines)
Drum Dryer (Suitable for Medium-to-Large Projects)

3. Pellet Forming System (Wood Pellet Machine)
Function: High-pressure rollers press sawdust into the ring die, achieving purely physical forming without additives.
The main shaft features a heavy-duty transmission design, suitable for long-term continuous operation. Formation rate: Up to 98%, pellet density approximately 1.1g/cm³

4. Cooling System (Counterflow Cooler)
Function: Cools hot pellets immediately after exiting the machine, preventing softening and breakage, improving hardness and packaging efficiency.
Advantageous Structure:
Counterflow airflow design prevents pellet breakage;
Automatic discharge system adapts to different particle sizes.

5. Screening Equipment (Vibrating Screen)
Function: Removes powder and debris from pellets, ensuring consistent finished product appearance.
Note: Powder can be recycled for re-pelleting, avoiding waste.

6. Packaging Equipment
Function: Weighing, bagging, and sealing improve shipping efficiency, suitable for commercial operations.

FAQ
Q1: What is the required space for the entire equipment set?
A: For a small production line (200 kg/h), the recommended space is at least 30 square meters; for a medium-sized line, 80-100 square meters is recommended, including areas for raw material storage and finished product storage.
Q2: What is the required moisture content of the raw materials?
A: The moisture content of the raw materials before entering the pelletizer should be controlled at 12%-15%. Excessive moisture will cause blockage or pelletizing failure.
Q3: How often does the pelletizer main unit need maintenance?
A: The die and rollers should be inspected for wear every 300-500 hours of operation. Lubricating with special grease is recommended and lubricated daily.
